PART I
ITEM 1.BUSINESS
Overview
We are engaged in the research and development of targeted, non-systemic therapies for the treatment of patients with gastrointestinal (“GI”) diseases. Non-systemic therapies are drugs that act locally, i.e. in the intestinal lumen, skin or mucosa, without reaching an individual’s systemic circulation. the intestinal lumen, skin or mucosa, without reaching an individual’s systemic circulation.
We are developing our product candidates for a host of GI diseases where there are significant unmet clinical needs and limited therapeutic options, resulting in painful, life threatening and discomforting consequences for patients. We are a company in the clinical stage of pharmaceutical development and our prospects must be considered in light of the uncertainties, risks, expenses and difficulties frequently encountered by companies in their early stages of operations. Our mission is to help protect the health and restore quality of life for the millions of people afflicted by these GI diseases.
We are currently focused on developing our pipeline of gut-restricted GI clinical product candidates, including the biologic adrulipase (formerly MS1819), a recombinant lipase enzyme designed to enable the digestion of fats and other nutrients, and niclosamide, an oral small molecule with anti-inflammatory properties.
Our adrulipase programs are focused on the development of an oral, non-systemic, biologic capsule for the treatment of exocrine pancreatic insufficiency (“EPI”) in patients with cystic fibrosis (“CF”) and chronic pancreatitis (“CP”). Our goal is to provide CF and CP patients with a safe and effective therapy to control EPI that is non-animal derived and offers the potential to dramatically reduce their daily pill burden. In November 2022 we filed a Phase 2b investigational new drug (“IND”) amendment for a bridging study using a new enteric microgranule formulation of adrulipase with the U.S. Food and Drug Administration (“FDA”). We initiated the Phase 2b monotherapy trial during the first quarter of 2023 and expect topline data in the third quarter of 2023.
Our niclosamide programs leverage proprietary oral and topical formulations to address multiple GI conditions, including inflammatory bowel diseases (“IBD”) indications. In 2022 we advanced two separate Phase 2 clinical programs of our niclosamide formulations, including FW-COV for Severe Acute Respiratory Syndrome Coronavirus 2 (“COVID-19”) GI infections, and FW-UP for ulcerative proctitis (“UP”) and ulcerative proctosigmoiditis (“UPS”).
We announced the completion of enrollment in the FW-COV trial in January 2022 and topline results in August 2022. In September 2022 we announced that we would no longer pursue the anti-viral COVID-GI clinical indication as a result of the mixed results from the FW-COVID-19 trial. Additionally, we are devoting fewer resources to the FW-UP/UPS niclosamide program due to inconclusive data from a small Phase 2 trial in Europe, the need for a new FDA-IND cleared protocol, and capital constraints.
We are continuing to develop FW-ICI-AC for Immune Checkpoint Inhibitor-associated colitis (“ICI-AC”) and diarrhea in advanced stage oncology patients and have received FDA clearance for an IND application for this program. We are also continuing two pre-IND programs of our niclosamide therapies for additional IBD indications, including FW-UC for ulcerative colitis (“UC”) and FW-CD for Crohn’s disease (“CD”).
Each drug candidate and clinical program is described below.
Adrulipase
Adrulipase is the active pharmaceutical ingredient (“API”) derived from Yarrowia lipolytica, an aerobic yeast naturally found in various foods such as cheese and olive oil that is widely used as a biocatalyst in several industrial processes. Adrulipase is a secreted lipase naturally produced by Yarrowia lipolytica, known as LIP2, that we are developing through recombinant DNA technology for the treatment of EPI associated with CF and CP. Lipases are enzymes that help with the digestion of lipids and fat.
-1-
We previously held the exclusive right to commercialize adrulipase in the U.S., Canada, South America (excluding Brazil), Asia (excluding China and Japan), Australia, New Zealand and Israel pursuant to a sublicense from Laboratories Mayoly Spindler SAS (“Mayoly”) under the Joint Research and Development Agreement (“JDLA”), which also granted us joint commercialization rights for Brazil, Italy, China and Japan. In March 2019, we purchased all rights, title and interest in and to adrulipase from Mayoly pursuant to the Mayoly Asset Purchas Agreement (“APA”), provided, however, Mayoly retained exclusive commercial rights in France and Russia.
Background
The pancreas is both an endocrine gland that produces several important hormones, including insulin, glucagon, and pancreatic polypeptide, as well as a digestive organ that secretes pancreatic juice containing digestive enzymes that assist with the absorption of nutrients and digestion in the small intestine.
The targeted indication of adrulipase is the treatment of EPI, which is observed when the exocrine functions of the pancreas are below 10% of normal. The targeted indication of MS1819 is the compensation of EPI, which is observed when the exocrine functions of the pancreas are below 10% of normal. The symptomatology of EPI is essentially due to the deficiency of pancreatic lipase, an enzyme that hydrolyses triglycerides into monoglycerides and free fatty acids. The pancreatic lipase enzymatic activity is hardly compensated by extra-pancreatic mechanisms, because gastric lipase has nearly no lipolytic activity in the pH range of the intestine. On the other hand, when they are impaired, the pancreatic amylase and protease (enzymes that break up carbohydrates (starches) and proteins, respectively) activities can be compensated by the salivary amylase, the intestinal glycosidase, the gastric pepsin, and the intestinal peptidases, all of which are components of the gastric juice secreted by the stomach walls. On the other hand, when they are impaired, the pancreatic amylase and proteases (enzymes that break up starches and protein, respectively) activities can be compensated by the salivary amylase, the intestinal glycosidase, the gastric pepsin, and the intestinal peptidases, all of which are components of the gastric juice secreted by the stomach walls. Lipid maldigestion due to lipase deficiency is responsible for weight loss, steatorrhea featured by greasy diarrhea, and fat-soluble vitamin deficiencies (i.e. A, D, E and K vitamins).
CP, the most common cause of EPI, is a long-standing inflammation of the pancreas that alters its normal structure and functions. In the U.S., its prevalence rate is of 42 cases per 100,000 inhabitants, resulting in approximately 132,000 cases. Approximately 60% of patients affected with CP display EPI, resulting in approximately 90,000 patients requiring substitution therapy in the U.S. In Western societies, CP is caused by chronic alcoholic consumption in approximately 55-80% of cases. Other relatively frequent etiologies include the genetic form of the disease that is inherited as an autosomal dominant condition with variable penetrance, pancreatic trauma and idiopathic causes.
CF, another dominant etiology of EPI, is a severe genetic disease associated with chronic morbidity and life-span decrease of most affected individuals. CF, another dominant etiology of EPI, is a severe genetic disease associated with chronic morbidity and life-span decrease of most affected individuals. In most Caucasian populations, CF prevalence is of 7-8 cases per 100,000 inhabitants, but is less common in other populations, resulting in more than 30,000 affected individuals in the U.S. and more than 70,000 affected individuals worldwide. CF is inherited as monogenic autosomal recessive disease due to the defect at a single gene locus that encodes the Cystic Fibrosis Transmembrane Regulator protein, or CFTR, a regulated chloride channel. Mutation of both alleles of this chloride channel gene results in the production of thick mucus, which causes a multisystem disease of the upper and lower respiratory tracts, digestive system, and the reproductive tract. The progressive destruction of the pancreas results in EPI that is responsible for malnutrition and contributes to significant morbidity and mortality. About 80-90% of patients with CF develop EPI, resulting in approximately 25,000-27,000 patients in the U.S. that require substitution therapy.
Current treatments for EPI stemming from CP and CF rely on porcine (pig derived) pancreatic enzyme replacement therapies (“PERTs”), which have been on the market since the late 1800s. PERTs are typically comprised of three digestive enzymes; lipases, proteases, and amylases. The PERT market is well established with estimated sales of approximately $1.4 billion in 2019 in the U.S. and has been growing for the past five years at a compound annual growth rate of approximately 20%. In spite of their long-term use, however, PERTs suffer from poor stability, formulation problems, possible transmission of conventional and non-conventional infectious agents due to their animal origins, and possible adverse events at high doses in patients with CF and limited effectiveness.
Pre-Clinical Program
The efficacy of adrulipase has been investigated in normal minipigs, which are generally considered to be a relevant model for digestive drug development because of their physiological similarities with humans and their omnivorous diet. Experimental pancreatitis was induced by pancreatic duct ligation, resulting in severe EPI with baseline CFA around 60% post-ligature. CFA is a measurement obtained by quantifying the amount of fat ingested orally over a defined time period and subtracting the amount eliminated in the stool to ascertain the amount of fat absorbed by the body. Pigs were treated with either adrulipase or enteric-coated PERTs, both administered as a single-daily dose. Pigs were treated with either MS1819 or enteric-coated PERTs, both administered as a single-daily dose.
-2-
At doses ranging from 10.5 to 211 mg, adrulipase increased the CFA by +25 to +29% in comparison to baseline (p<0.05 at all doses), whereas the 2.5 mg dose had milder activity. Similar efficacy was observed in pigs receiving 100,000 U lipase of enteric-coated porcine pancreatic extract. These findings demonstrate the in vivo activity of adrulipase in a relevant in vivo model at a level similar to the PERTs at dosages of 10.5mg or greater.
To date, two non-clinical toxicology studies have been conducted. To date, two non-clinical toxicology studies have been conducted. Both show that adrulipase lipase is clinically well tolerated at levels up to 1000mg/kg in rats and 250 mg/kg in minipigs up to 13 weeks. Both show that MS1819 lipase is clinically well tolerated at levels up to 1000mg/kg in rats and 250 mg/kg in minipigs up to 13 weeks. Adrulipase is therefore considered non-toxic in both rodent and non-rodent species up to a maximum feasible dose of 1,000 mg/kg/day in the rats over six months of administration. MS1819 is therefore considered non-toxic in both rodent and non-rodent species up to a maximum feasible dose (“MFD”) of 1,000 mg/kg/day in the rats over six months of administration.
Clinical Program
We are developing adrulipase for two principal therapeutic indications: (i) children and adults affected by CF, and (ii) adult patients with CP. We have determined to initially pursue the adult indication in CF.
Chronic Pancreatitis
During 2010 and 2011, a phase 1/2a clinical trial of adrulipase was conducted in conjunction with Mayoly in a single center in France. The study was an exploratory study mainly designed to investigate the safety of adrulipase and was a randomized, double blind, placebo controlled, parallel clinical trial in 12 patients affected with CP or pancreatectomy and severe EPI. The study was an exploratory study mainly designed to investigate the safety of MS1819-FD (freeze-dried) and was a randomized, double blind, placebo controlled, parallel clinical trial in 12 patients affected with CP or pancreatectomy and severe EPI. The primary efficacy endpoint of the study was defined as the relative change in steatorrhea (an established surrogate biomarker of EPI correction) in comparison to baseline. The study found that adrulipase was well tolerated with no serious adverse events. The study found that MS1819 was well tolerated with no serious adverse events. Only two adverse events were observed: constipation (two patients out of eight with adrulipase) and hypoglycemia (two patients out of eight with adrulipase, and one patient out of four with placebo). Only two adverse events were observed: constipation (two patients out of eight with MS1819) and hypoglycemia (two patients out of eight with MS1819, and one patient out of four with placebo). A non-statistically significant difference of the primary endpoint, possibly due to the small group size, was found between the two groups both in intention-to-treat, a group that included three patients who received the in-patient facility study diet but did not fulfill the protocol’s inclusion criteria, and per-protocol analysis. This study was not designed, nor did it aim, to demonstrate statistically significant changes of CFA or steatorrhea under adrulipase.
We received regulatory approval in Australia and New Zealand in 2016, with the addition of a 2018 regulatory approval in France, to conduct a Phase 2 multi-center dose escalation study of adrulipase in CP and pancreatectomy. We received regulatory approval in Australia and New Zealand in 2016, with the addition of a 2018 regulatory approval in France, to conduct a phase II multi-center dose escalation study of MS1819 in CP and pancreatectomy. The primary endpoint of this study was to evaluate the safety of escalating doses of adrulipase in 11 CP patients. The primary endpoint of this study was to evaluate the safety of escalating doses of MS1819 in 11 CP patients. The secondary endpoint was to investigate the efficacy of adrulipase in these patients by analysis of the CFA and its change from baseline. The secondary endpoint was to investigate the efficacy of MS1819 in these patients by analysis of the CFA and its change from baseline. In September 2018, we announced that in pre-planned analyses, both the study’s primary and secondary endpoints were reached with a statistically significant (p=0.002) improvement in the CFA of 21.8%, in a per protocol analysis, with the highest evaluated dose of 2,240 mg/day of adrulipase. Statistical significance of the trial results is typically based on widely used, conventional statistical methods that establishes the p-value of the results. A p-value of 0.05 or less is required to demonstrate statistical significance. As such, these CFA levels are considered to be statistically significant.
Cystic Fibrosis Monotherapy
In October 2018, the FDA cleared our IND application for adrulipase in patients with EPI due to CF. In December 2018, we initiated the Phase 2 OPTION Bridging Dose Study to investigate adrulipase in CF patients with EPI and in February 2019, we dosed the first patients. The Phase 2 OPTION Bridging Dose Study investigated the safety, tolerability and efficacy of adrulipase in a head-to-head comparison against the current PERT standard of care. The OPTION Bridging Dose Study employed a six-week non-inferiority CFA primary efficacy endpoint comparing adrulipase to PERTs.
In September 2019, we announced positive results from the OPTION Bridging Dose Study. Results showed that the primary efficacy endpoint of CFA was comparable to the CFA in a prior Phase 2 study in patients with CP, while using the same dosage of adrulipase. Results showed that the primary efficacy endpoint of CFA was comparable to the CFA in a prior Phase 2 study in patients with CP, while using the same dosage of MS1819. The dosage used in the OPTION Cross-Over Study was 2.2 grams per day, which was determined in agreement with the FDA as a bridging dose from the highest safe dose used in the Phase 2 CP dose escalation study. The dosage used in the OPTION Bridging Dose Study was 2.2 grams per day, which was determined in agreement with the FDA as a bridging dose from the highest safe dose used in the Phase 2 CP dose escalation study. Although the study was not powered for statistical significance, the data demonstrated meaningful efficacy results, with approximately 50% of the patients showing CFAs high enough to reach non-inferiority with standard PERTs. Additionally, the CNA was comparable between the adrulipase and PERT arms, 93% vs. 97%, respectively, in the OPTION Bridging Dose Study. 97%, respectively, in the OPTION Cross-Over Study. This important finding confirms that protease supplementation is not likely to be required with adrulipase treatment. A total of 32 patients, ages 18 or older, completed the OPTION Bridging Dose Study. A total of 32 patients, ages 18 or older, completed the OPTION Cross-Over Study.

In October 2019, the CFF DSMB completed its review of our final results of the OPTION Bridging Dose Study and found no safety concerns for adrulipase and supported our plan to proceed to the Phase 2b OPTION 2 Trial. In December 2019, we submitted the clinical trial protocol to the existing IND at the FDA. In December 2019, the Company submitted the clinical trial protocol to the existing IND at the FDA. In April 2020, we received approval to conduct the OPTION 2 Trial in Therapeutics Development Network clinical sites in the U.S.
The OPTION 2 Trial was designed to investigate the safety, tolerability and efficacy of adrulipase (2.2 gram and 4.4 gram doses in enteric capsules) head-to-head versus the current standard of care, PERT pills. The OPTION 2 Trial was an open-label, crossover study, conducted in 15 sites in the U.S. and Europe. Enrollment included a total of 30 CF patients 18 years or older. Adrulipase was administered in enteric capsules to provide gastric protection and test for optimal delivery of enzyme to the duodenum. Patients were first be randomized into two cohorts: the adrulipase arm, where they received a 2.2 gram daily oral dose of adrulipase for three weeks; or the PERT arm, where they received their pre-study dose of PERT pills for three weeks. After three weeks, stools were collected for analysis of CFA. Patients were then crossed over for another three weeks of the alternative treatment. After three weeks of cross-over therapy, stools were again collected for analysis of CFA. A parallel group of patients was randomized and studied in the same fashion using a 4.4 gram daily dose of adrulipase. All patients were followed for an additional two weeks after completing both crossover treatments for post study safety observation. Patients were assessed using descriptive methods for efficacy, comparing CFA between adrulipase and PERT arms, and for safety.
In January 2021, we announced an additional study arm in OPTION 2 Trial using an immediate release adrulipase capsules in order to identify the optimal dose and delivery method of adrulipase. This extension phase tested patients 18 years or older, who have already completed the crossover phase, at higher doses relative to the previously conducted OPTION Bridging Dose Study. This allowed us to compare data from the existing crossover arm using enteric (delayed release) capsules with data from the new immediate release extension arm.
In March 2021 we announced topline OPTION 2 data. The trial demonstrated that adrulipase was safe and well-tolerated and data from OPTION 2, and the other adrulipase Phase 2 clinical trials, demonstrated drug activity. However, OPTION 2 did not consistently meet the primary efficacy endpoint. Some patients were able to achieve CFA at levels beyond what is required to demonstrate non-inferiority with PERT therapies, but the majority did not.
We believe that the underlying cause of the drug’s uneven efficacy performance in the OPTION 2 trial was the enteric capsule formulation. While the enteric coating protected the capsule from breaking down in the stomach acid, it also appeared to dissolve too slowly in the small intestine to release the lipase enzyme in time to aid with proper digestion and nutrient absorption.
In August 2021 we announced that we would begin development of a new enteric microgranule formulation of adrulipase. The new formulation is planned to be administered with food as an oral capsule that dissolves in the stomach and disperses acid-resistant micro-granules that thoroughly mix with food during the digestion process. The resultant mixture then passes to the small intestine where the lipase enzyme breaks up fat molecules so that they can be absorbed. We completed the reformulation work in the second half of 2022.
In November 2022 we announced that we had filed an IND amendment with the FDA for a Phase 2b bridging study with the new enteric microgranulation formulation of adrulipase. The new trial is designed to investigate the safety, tolerability and efficacy of the new formulation of adrulipase. It is an open-label study that will be conducted at three sites in the U.S. A total of 12 cystic fibrosis patients, 18 years or older are expected to be enrolled. The trial design employs a dose titration strategy. Patients will be screened at baseline to ensure that they have a coefficient of fat absorption (CFA) of at least 80%. Eligible patients will then be switched from their commercial enzyme product to adrulipase. Each patient will be started on a low dose of adrulipase. If the patient is not clinically controlled, the patient will be switched to a medium dose, and if not controlled on this dose, the patient will be advanced to a high dose. The titrations will be carried out over a three-week period, after which a CFA will be obtained. End of study CFAs will be compared to the baseline CFAs in a descriptive fashion. A post treatment safety visit will be conducted one week after completing the treatment period.
Following FDA review of the IND amendment, we initiated the Phase 2b pilot monotherapy trial during the first quarter of 2023 and anticipate topline data in the third quarter of 2023.

Combination Therapy
We launched the Phase 2 Combination Trial in Hungary in July 2019 to investigate adrulipase, in combination with PERT, in CF patients who suffer from severe EPI but continue to experience clinical symptoms of fat malabsorption despite taking the maximum daily dose of PERTs. The Combination Trial is designed to investigate the safety, tolerability and efficacy of escalating doses of adrulipase (700 mg, 1120 mg and 2240 mg per day, respectively), in conjunction with a stable dose of PERTs, in order to increase CFA and relieve abdominal symptoms. The Combination Trial is designed to investigate the safety, tolerability and efficacy of escalating doses of MS1819, in conjunction with a stable dose of PERTs, in order to increase CFA and relieve abdominal symptoms in uncontrolled CF patients. In October 2020, we opened a total of five clinical sites in Turkey and dosed the first patients in November 2020. In March 2021, we reached targeted minimum enrollment of 18 patents.
We announced positive interim data on the first five patients in the Combination Trial in August 2020. The primary efficacy endpoint was met, with CFAs greater than 80% for all patients across all visits. For secondary efficacy endpoints, we observed that stool weight decreased, the number of stools per day decreased, steatorrhea improved, and body weight increased. Additionally, no serious adverse events were reported.
In August 2021, we announced topline data collected from the 20 patients enrolled in the study. The data indicated that adrulipase in combination with PERT led to clinically meaningful improvements in CFA, the primary efficacy endpoint. Patients showed an average gain of more than six percentage points from baseline, compared to the five-point improvement in CFA cited by the clinical literature as clinically significant. The study also demonstrated positive improvements in weight gain and other secondary endpoints.
We believe a combination therapy of PERT and adrulipase has the potential to: (i) correct macronutrient and micronutrient maldigestion; (ii) eliminate abdominal symptoms attributable to maldigestion; and (iii) sustain optimal nutritional status on a normal diet in CF patients with severe EPI. A combination therapy of PERT and MS1819 has the potential to: (i) correct macronutrient and micronutrient maldigestion; (ii) eliminate abdominal symptoms attributable to maldigestion; and (iii) sustain optimal nutritional status on a normal diet in CF patients with severe EPI. We developed a new enteric microgranule formulation and initiated a Ph2b monotherapy trial in the first quarter of 2023. We expect topline date in the third quarter of 2023. Depending on the results of this trial, we may elect to conduct further combination therapy trials using the new formulation.
Niclosamide
Niclosamide, a pro-inflammatory pathway inhibitor, is a prescription small molecule drug that has been safely used on millions of patients. Niclosamide is listed as an essential medicine by the World Health Organization (WHO). In the U.S., niclosamide was approved by the United States Food and Drug Administration (“FDA”) in 1982 for the treatment of intestinal tapeworm infections. Niclosamide’s activity as an antihelminthic results from direct action in the intestinal lumen where it disrupts a parasitic metabolic function called oxidative phosphorylation, killing parasites. Niclosamide has been commercially available worldwide for more than 50 years as 500mg single-dose tablets intended for use in pediatric and adult populations, at a dose rate of 2g per adult or child over six years of age. No safety issues have ever been identified. In addition to its antihelminthic activity, niclosamide has demonstrated novel anti-inflammatory properties.
We believe niclosamide, and more specifically our proprietary and patent-pending micronized niclosamide formulation, has the potential to be an ideal therapeutic to treat multiple GI indications due to the following favorable properties:
(i) | it has a reduced particle size (D(90) between 5 and 9 µM) as compared to regular non-micronized niclosamide (approximately D(90) ≥ 60µM) with greater surface to solvent ratio; |
(ii) | low oral bio-availability with minimal systemic absorption / exposure; |
(iii) | improved dissolution with broader distribution allowing for higher local GI concentrations (up to approximately 200 times based on preclinical study results); and |
(iv) | it exhibits anti-inflammatory effects while avoiding steroid-related complications and adverse events. |

Scientific Background
Recent discoveries in immune cell metabolism suggest that it may be possible to selectively target disease-causing immune cells to treat inflammatory diseases without unwanted side effects associated with broad-based immunosuppression. Research indicates that IBD, including ulcerative colitis, ulcerative proctitis/proctosigmoiditis and Crohn’s disease, is driven by pathogenic Th17 cells, which release a cascade of local cytokines that in turn cause inflammation in bowel wall tissues.
Th17 cells rely on a cellular process called oxidative phosphorylation to survive. Niclosamide is known to disrupt the oxidative phosphorylation in the mitochondria of pathogenic Th17 cells in a manner that selectively induces apoptosis of pathogenic Th17 cells, overcoming their inherent resistance to cell death. This effect is mild enough that it does not interfere with normal cells. By killing Th17 cells, niclosamide may reduce inflammation and calm the gut, selectively killing pathogenic, inflammatory cells while leaving healthy cells untouched.
Niclosamide has demonstrated beneficial effects in numerous cell culture studies using cells obtained by biopsy of inflamed bowel tissues from IBD patients, and also in animal models of IBD.
Our suite of proprietary, gut-restricted niclosamide product candidates are designed to target the metabolism of disease-causing Th17 cells to potentially halt or delay the progression of disease, stop flare-ups, and address patient needs at all stages of IBD, from mild to severe, and for cancer patients with ICI-AC.
Inflammatory Bowel Disease Background
IBD is an umbrella term used to describe disorders that involve chronic inflammation of the digestive track. IBD affects approximately 3 million people in the U.S. annually. IBD is divided into two main classes of gastrointestinal inflammatory diseases: (i) ulcerative colitis (UC), including ulcerative proctitis (UP) and ulcerative proctosigmoiditis (UPS), and (ii) Crohn’s Disease (CD). There are similarities between UC and CD, such as immunopathology, and equal distribution between males and females. However, there are also notable differences. However, there are simplified standards. UC is generally limited to the colon, while CD may occur anywhere in the small or large intestine. UC usually affects continuous mucosal surfaces, while CD is patchier, with areas of normal bowel mucosa separating the inflammatory patches. Importantly, CD often involves deep bowel tissues and can lead to fistulas into the abdominal cavity or out to the skin surface. CD requires surgical intervention more often than UC. While medical treatments for UC and CD are generally similar, CD is much less responsive.
FW-COV Program for COVID-19 GI Infections
The COVID-19 pandemic is a global public health emergency caused by the SARS-CoV-2 virus. An increasing volume of convergent evidence indicates that GI infection and fecal-oral transmission of SARS-CoV-2 are important factors in the clinical presentation, virology and epidemiology of COVID-19. There is currently no etiological treatment for COVID-19 GI effects. As a result, we believe there is an unmet therapeutic need for safe and effective treatment of these effects.
A study published in July 2020 in Antimicrobial Agents and Chemotherapy, an American Society for Microbiology journal (Jeon et. Al, 2020) examined a small set (n=49) of FDA-approved drugs that were selected based on either having known activity against SARS-CoV or being recommended by infectious disease experts for activity against the SARS-CoV-2 virus. Results from this study indicated that niclosamide was the most potent of all agents tested in a Vero cell cytopathic assay with an IC50 value of 0.28 µM. For comparison, in terms of potency, niclosamide out-performed reference compounds chloroquine, lopinavir, and remdesivir with IC50 values of 7.28, 9.12, and 11.41 µM, respectively. IC50 is a quantitative measure that indicates how much of a particular inhibitory substance (e.g. a drug) is needed to inhibit, in vitro, a given biological process or biological component by fifty percent. Thus, niclosamide is approximately 40-fold more potent in vitro than VEKLURY® (remdesivir), an antiviral drug marketed by Gilead Sciences Inc. that received FDA approval in October 2020 for use in adult and pediatric patients for the treatment of COVID-19 requiring hospitalization.
Following oral administration, niclosamide is poorly absorbed, which results in a majority of the administered dose remaining in the GI tract. We believe this basic property of niclosamide, when combined with micronized niclosamide in the drug product to accelerate dissolution, will enable this drug product to achieve pharmacologically effective concentrations of niclosamide in the GI tract while having almost no bioavailability, potentially enhancing efficacy and safety.

An IND for FW-COV micronized niclosamide for COVID-19 GI infections was cleared by the FDA in September 2020. In April 2021, we initiated our Phase 2 RESERVOIR clinical trial for the treatment of COVID-19 related GI infections. The Phase 2 RESERVOIR clinical trial is a two-part, two-arm, randomized, placebo-controlled study examining the safety and efficacy of micronized oral niclosamide tablets in patients with COVID-19 GI infection. The two primary objectives of the RESERVOIR trial are to confirm the safety of niclosamide in the treatment of patients with COVID-19 GI infection and to demonstrate efficacy in clearing the SARS-CoV-2 virus from the GI tract.
Part 1 of the trial studied 9 patients with COVID-19 and diarrhea. Patients were randomized (2:1 niclosamide: placebo), treated for 14 days and observed closely for any signs of safety issues. In September 2021, we announced positive results from an independent Data Monitoring Committee review of the interim safety data. The Data Monitoring Committee also approved initiating patient enrollment in Part 2.
Part 2 of the trial studied approximately 150 patients in the U.S., Ukraine and India with mild or moderate COVID-19. Patients were randomized to either niclosamide, 400 mg tablets, three times a day, or placebo tablets three times a day. After 14 days of treatment, patients are taken off study drugs and remain on study observation for up to 6 months. Our trial samples from the clinical trial site in Ukraine have been completed and transported out of Ukraine.
The primary efficacy measure of the RESERVOIR trial is the rate of fecal SARS-CoV-2 virus clearance (rectal swab or stool sample) assessed by RT-PCR, comparing the niclosamide arm to the placebo arm for up to six months. These long-term observation data could indicate that niclosamide treatment has the potential to improve ‘long haul’ COVID-19 symptoms by decreasing viral load in the GI tract. There is evidence to support that the GI tract may be a possible reservoir for persistence and fecal spread of COVID-19 because ACE-2, the entry receptor for COVID-19, is highly expressed on GI cells.
In January 2022, we announced completion of patient enrollment for Part 2 of the RESERVOIR trial. In April 2022 the Company announced that top-line data results from the trial were mixed. FW-COV was demonstrated to be very safe with no drug-related serious adverse events (SAEs) reported by the more than 150 patients who participated in the trial. However, the efficacy endpoint in this trial – the ability of FW-COV to remove the SARS-CoV-2 (SARS2) virus from the digestive tract as measured by viral presence in the patient’s stool – did not demonstrate statistical significance when compared to placebo. As a result, the Company decided not to further pursue niclosamide clinical studies for the anti-viral treatment of COVID-GI.
FW-UC for Ulcerative Colitis (UC)
UC is an IBD that causes inflammation and ulcers (sores) in the digestive tract. UC generally affects the innermost lining of the large intestine (colon). UC affects approximately 830,000 patients in the U.S. annually and approximately 84% or 700,000 have mild to moderate disease. The immunopathology of UC is complex and is generally considered to be caused by a dysregulated immune system. There is evidence that a hereditary trait is involved. While the cause is not known, many researchers believe that invasive bacteria or virus in the bowel wall sets off an abnormal response by local T lymphocytes. Normally, a subgroup of lymphocytes called Th17 cells protect the bowel wall from microbial invaders. However, in patients with UC, these Th17 cells become pathogenic and release a cascade of local cytokines, which in turn cause inflammation in bowel wall tissues. This persistent inflammation causes tissue damage, and clinical symptoms. Clinical symptoms include abdominal pain, diarrhea, which is sometimes bloody, intermittent fever, anemia, and weight loss, and symptoms usually develop over time, rather than suddenly.
Severity of UC is generally classified as mild, moderate or severe. Mild disease is treated by sulfasalazine and 5-ASA’s, most commonly mesalamine. These may be given orally or rectally and are modestly potent anti-inflammatory agents. While inexpensive and well tolerated, only about 50% of UC patients will maintain a clinical response to these agents. Non-responders or relapsers will progress to moderate or even severe disease.
Patients failing on 5-ASA’s are usually placed onto steroid therapy, such as budesonide or prednisone, risking the well-known side effects of steroids. Failing, or not tolerating steroids leads to treatment with much more potent and expensive immunosuppressive agents such as anti-TNFs, or newer agents such as Entyvio® or Xeljanz®. We believe there is an unmet medical need for a well-tolerated, effective therapeutic for patients who fail first line treatment with 5-ASAs.
Our initial clinical trial in UC involves patients with ulcerative proctitis (UP) and ulcerative proctosigmoiditis (UPS), who are being treated with a topical rectal formulation, which is currently in a Phase 1b/2a clinical trial.

We intend to commence the clinical development of FW-UC, employing an oral tablet formulation in a Phase 1 clinical trial for subjects with UC in 2023, subject to successful results from Stage 2 of the FW-UP Phase 1b/2a clinical trial.
FW-UP Program for Ulcerative Proctitis (UP) and Ulcerative Proctosigmoiditis (UPS)
UP and UPS are two types of UC, a chronic inflammatory bowel disease consisting of fine ulcerations in the inner mucosal lining of the large intestine that do not penetrate the bowel muscle wall. UPS causes inflammation in the colon and rectum, while UP is confined only to the rectum. Symptoms include weight loss, fatigue, abdominal pain and cramps, rectal pain and bleeding, and diarrhea, although constipation can also develop as the body struggles to maintain normal bowel function. UP and UPS affect approximately 200,000 patients in the U.S. annually.
UP and UPS can occur at any point throughout life, with a high occurrence in young children and then again around 40-50 years of age. Progression of this disease to ulcerative colitis, extending farther up the bowel to involve the sigmoid colon, occurs in about 30-50% of patients. UP and UPS allow convenient clinical management and observation by local sigmoidoscopy. Although there is a range of treatments to help ease symptoms and induce remission, there is no cure.
We are developing FW-UP, a niclosamide-based, small molecule anti-inflammatory inhibitor therapy in enema formulation for the potential treatment of UP and UPS. FW-UP is currently being investigated in a three-stage Phase 1b/2a clinical trial in Europe studying the safety and potential efficacy of niclosamide in patients with UP and UPS.
Stage 1 of the trial studied 17 subjects with UP who had failed first line therapy with 5-ASAs. They were treated for six weeks with low dose FW-UP niclosamide rectal enemas twice a day. Preliminary results demonstrated that FW-UP niclosamide enemas were well tolerated, with a durable therapeutic effect. The efficacy endpoint was to achieve a clinical remission, defined as a Modified Mayo Score of 2 or less. A clinical remission rate of 59% was achieved, which is higher than currently approved second line therapy with budesonide (38% to 44%).
Stage 2 of the trial is designed to study a higher dose of niclosamide enema twice daily for six-weeks. Stage 2 enrollment was initiated in September 2021 and will enroll 28 patients in a placebo-controlled study to compare FW-UP, administered as an enema twice daily at a dose of 450 mg, to placebo enemas twice daily.
In September 2022 we announced that we would devote fewer resources to the FW-UP/UPS niclosamide program due to inconclusive data from Stage 2 of the Phase 2 trial in Europe, the need for a new FDA-IND cleared protocol and capital constraints.
We plan to initiate a new Phase 2 UP/UPS trial under an FDA IND cleared protocol upon securing sufficient financial resources.
FW-ICI-AC for Immune Checkpoint Inhibitor Colitis (ICI-AC)
Immune checkpoint inhibitors (“ICIs”) are monoclonal antibodies that target down-regulators of the anti-cancer immune response and have significantly affected the treatment of a variety of malignancies. However, many immune-related adverse events, especially diarrhea and colitis, limit their use. A 2019 study titled, “Immune checkpoint inhibitor-induced colitis: A comprehensive review,” published in World Journal of Clinical Cases (Sol et.al, 2019) estimated the incidence of IMC ranges from 1% to 25% depending on the type of ICI and whether they are used in combination. A 2017 study titled “Incidence of immune checkpoint inhibitor-related colitis in solid tumor patients: a systematic review and meta-analysis” published in Oncoimmunology (Wang et.al, 2017) estimated that approximately 44%, or 260,000 patients with advanced and metastatic tumors were eligible to receive ICIs. Further, approximately 30% of ICI patients develop diarrhea, which can progress to colitis. The onset of diarrhea in ICI-AC patients occurs within six to seven weeks and progressively worsens, and the progression to colitis is rapid and unpredictable.
In patients taking Yervoy® (ipilimumab), between 25% to 30% developed diarrhea and approximately 8% to 12% developed colitis, as reported in a peer-reviewed article, “Immune-checkpoint inhibitor-induced diarrhea and colitis in patients with advanced malignancies: retrospective review at MD Anderson” published in the Journal for ImmunoTherapy of Cancer (Wang et. al,, 2018). Moreover, there is a treatment trend towards the use of combination ICI therapies (for example combining Yervoy® and Opdivo®), which is believed to lead to a concomitant increase in both diarrhea and colitis.
-8-
We believe there currently is no approved treatment for Grade 1 colitis. The recommended treatment for Grade 2 or more severe colitis is administration of corticosteroids, or treatment with certain immunosuppressive biologics, while withholding ICI therapy (National Cancer Institute, 2020). The impact of this colitis complication and treatment may reduce the goal of progression-free cancer survival. We believe there is an unmet medical need and an oral, non-absorbed therapeutic, such as our FW-ICI-AC niclosamide, for Grade-1 colitis (diarrhea) which may prevent progression to Grade 2 or more severe disease.
In October 2021, we received FDA IND clearance to commence our Phase 1b/2a PASSPORT ICI-AC clinical trial using an oral immediate-release tablet formulation of niclosamide for Grade 1 and Grade 2 colitis and diarrhea in oncology patients receiving treatment with ICIs.
The Phase 2a PASSPORT clinical trial is designed as a double-blind, placebo-controlled study to determine the safety, tolerability, and preliminary efficacy of FW-ICI-AC in the treatment of immune checkpoint inhibitor-associated colitis (ICI-AC) and diarrhea in advanced cancer patients. 60 patients are planned to be enrolled in the trial and divided into two arms (30 patients per arm). One arm will receive FW-ICI-AC three times daily for two weeks, while the other arm will receive placebo three times daily for two weeks. Following treatment, each patient will enter a four-week evaluation period. The primary endpoint of the trial is safety and tolerability of FW-ICI-AC. Additional endpoints will measure early signals of efficacy, including resolution of the patient’s diarrhea, sparing of steroids, and prevention of disease progression.
We plan to initiate the PASSPORT trial in the U.S. upon securing sufficient financial resources.
FW-CD for Crohn’s Disease (CD)
While the immunopathology of CD resembles that of UC, the location of disease, the response to treatment and the overall morbidity are different, as CD is more difficult to manage. Patient response to standard therapy is more variable than in UC, thus making clinical management more challenging. In UC, a reasonably clear course of disease from mild to moderate severity can be predicted based upon response to first line treatment. In CD, first line treatment often includes more immunosuppressive agents, such as steroids, immunomodulators, and anti-TNF agents as compared to the 5-ASAs used for first line in UC.
CD affects approximately 660,000 patients in the U.S. annually and approximately 76% or 500,000 have mild to moderate disease. We believe FW-CD, an oral niclosamide-based small molecule anti-inflammatory inhibitor therapy can be an important therapeutic in the treatment of mild to moderate CD, with the goal of reducing steroid and immunomodulators treatments.
We plan to initiate the PASSPORT trial in the U.S. upon securing sufficient financial resources. We intend to commence clinical development of FW-CD in a Phase 2a clinical trial, subject to the successful completion of a FW-UC Phase 1 clinical trial.

Competition
The pharmaceutical and biotechnology industries are characterized by rapidly evolving technology and intense competition. Many companies of all sizes, including major pharmaceutical companies and specialized biotechnology companies, are engaged in the development and commercialization of therapeutic agents designed for the treatment of the same diseases and disorders that we target. Many of our competitors have substantially greater financial and other resources, larger research and development staff and more experience in the regulatory approval process. Moreover, potential competitors have or may have patents or other rights that conflict with patents covering our technologies.
Adrulipase
With respect to adrulipase, if approved, we would compete with PERTs (pancrelipase), a well-established market that is currently dominated by a few large pharmaceutical companies, including CREON® marketed by AbbVie Inc., ZENPEP® sold to Nestlé S.A. by Allergan plc. in January 2020, PANCREAZE® marketed by VIVUS, Inc. and PERTZYE® marketed by Chiesi Farmaceutici S.p.A. There are currently six PERT products that have been approved by the FDA for sale in the U.S. We believe our ability to compete in this market, if we are successful in developing and obtaining regulatory approval to market adrulipase, will depend on our ability (or that of a future corporate partner) to convince patients, their physicians, healthcare payors and the medical community of the benefits of using a non-animal-based product to treat EPI, as well as by addressing other shortcomings associated with PERTs, including a large pill burden.
Niclosamide
With respect to FW-COV, our oral micronized formulation of niclosamide for COVID-19 GI infections, if approved, would compete with currently approved antivirals, including Pfizer’s Inc.’s PAXLOVIDTM, Merck & Co. Inc. and Ridgeback Biotherapeutics’ molnupiravir, VEKLURY® (remdesivir) marketed by Gilead Sciences, Inc. and vaccines, including those marketed by Pfizer Inc. and BioNTech SE, Moderna, Inc. Johnson & Johnson and AstraZeneca plc. There are also several therapeutic and vaccine candidates in various stages of development that may obtain regulatory approval for the treatment or prevention of COVID-19 infections. Additionally, there are currently ongoing clinical studies using niclosamide by ANA Therapeutics (acquired by NeuroBo Pharmaceuticals, Inc.), Daewoong Pharmaceuticals Co Ltd, and Union Therapeutics A/S, among others at various stages of development. We believe our approach to target COVID-19 GI infections is differentiated. We believe our ability to compete in this market, if we are successful in developing and obtaining regulatory approval to market FW-COV, will depend on our ability (or that of future corporate partners) to convince patients, their physicians, healthcare agencies and payors and the medical community of the benefits of using FW-COV to treat patients with COVID-19 infections with GI symptoms.
With respect to FW-ICI-AC, our oral micronized formulation and niclosamide for ICI-AC, if approved, would compete with both oral and intravenous administered steroids as well as hospital-based infusions of biologics, including infliximab and vedolizumab. We believe our ability to compete in this market, if we are successful in developing and obtaining regulatory approval to market FW- ICI-AC, will depend on our ability (or that of future corporate partners) to convince patients, their physicians, healthcare agencies and payors and the medical community of the benefits of using a non-steroidal, non-biologic therapeutic option for the treatment of ICI-AC.
-12-
With respect to FW-UP and FW-UC, our topical formulation of niclosamide for UP, if approved, would compete with sulfasalazines and 5-ASAs, for the treatment of mild disease, steroids, including budesonide and prednisone, azathioprine, 6-mercaptopurine, and methotrexate for the treatment of moderate disease, and Anti-TNFs, Entyvio® (vedolizumab), Xeljanz® (Tofacitinib); Stelara® (Ustekinumab) for the treatment of severe disease. We believe our ability to compete in this market, if we are successful in developing and obtaining regulatory approval to market FW-UP and FW-UC, will depend on our ability (or that of future corporate partners) to convince patients, their physicians, healthcare agencies and payors and the medical community of the benefits of using a non-steroidal, non-biologic therapeutic option to prevent the advancement disease requiring more toxic immunosuppressive therapeutic option for the treatment of mild and moderate UP and UC.
Government Regulation and Product Approval
Government authorities in the United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of products such as those we are developing. To date, our internal research and development efforts have been conducted in France. We expect to conduct late-stage development work, including clinical trials for niclosamide and adrulipase in both the United States and Europe, as North America is our principal target market for our product candidates that we may successfully develop.
U.S. Government Regulation
In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing regulations, and biologics under the FDCA and the Public Health Service Act, or PHSA, and its implementing regulations. FDA approval is required before any new unapproved drug or dosage form, including a new use of a previously approved drug, can be marketed in the United States. Drugs and biologics are also subject to other federal, state and local statutes and regulations. If we fail to comply with applicable FDA or other requirements at any time during the drug development process, clinical testing, the approval process or after approval, we may become subject to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, license suspension or revocation, withdrawal of an approval, warning letters, product recalls, product seizures, placement on Import Alerts, debarment of personnel, employees or officers, total or partial suspension of production or distribution, injunctions, fines, civil penalties or criminal prosecution.
